Question

In Kaminari, this works:

<%= paginate @posts %>

But if I do something like:

<%= paginate @user.posts %>

I get

undefined method `current_page' for #<Class:0x58378e0>      

How do I fix this? I heard inherited_resources helped, but I don’t know how to use it to fix this bug.

Answer 1

Because in the first version @posts was probably the result of running something like

   @posts = Post.page(2).per(50)

So Kaminari returned an array like object, which paginate helper method expects.

When you call @user.posts directly you are in fact just loading a plain old ActiveRecord association.

The short answer is that you need to let Kaminari generate the variable you are in fact using with the paginate helper method
